Tutorial

Here's a simple summary of what this script does:

1. When the webpage first loads, it looks for an HTML element on the page that has the attribute `ms-code-logout-timer`. It expects the content of this element to be a time like "10:00" (for 10 minutes) or "00:30" (for 30 seconds).

2. It then starts a countdown from the specified time. This countdown is displayed on the page by updating the content of the `ms-code-logout-timer` element every second.

3. The script also keeps an eye on any activity on the page, such as moving the mouse, pressing a key, or touching the screen (on a touch-enabled device). If it detects any of these activities, it resets the countdown back to its original starting value.

4. If the countdown ever reaches zero, it will automatically redirect the user to a page with the URL "/expired". After the redirection, the countdown restarts from the initial time.

5. Lastly, any member who lands on the /expired page will be logged out automatically.
